Some operations such as trenching result in confined spaces. Shoring systems are necessary to protect these spaces and reduce the chance for cave-ins.
A trench is a narrow excavation below the ground. Trenches are typically deeper than they are wide; however, the width of a trench is less than 15 feet.
A shoring system consists of a structure that supports the sides of an excavation and is designed to prevent cave-ins.
Employees must follow all the requirements associated with confined spaces when working within trenches.
